 Product Description


Leica GS18 I - GNSS Rover with Visual Positioning

The GS18 I is the world’s first GNSS RTK rover with integrated Visual Positioning technology.

The Leica GS18 I is a fast, safe and easy to use GNSS RTK rover, with the ability to measure a large amount of remote points from a safe distance.

This is made possible using Visual Positioning technology that is based on the seamless integration of GNSS, IMU and a camera.

The GS18 I gives the ability to measure points either with the pole as a traditional GNSS rover, or by measuring in captured images in the field and in the office, all with survey-grade accuracy.





The Leica GS18 I is an accurate and easy to use GNSS RTK Rover. It utilises highly innovative Visual Positioning technology based on seamless integration of GNSS, IMU and a camera. It enables you to measure survey grade points in images on site and in the office. Create point clouds from captured data with Infinity to expand possibilities even further.



Designed to measure large amounts of points efficiently. Leica GS18 I allows you to capture images and measure hundreds of points within minutes, also places which cannot be physically accessed. Using images to measure these points, allows you to reduce time spent onsite and cut down re-work: once you captured the site, you have every detail measured.




Imaging power has changed the rules of the game. By having the power to measure what you see, you can now reach places you couldn’t before without switching tools or climbing through obstacles. That gives you the flexibility in the field, frees up equipment and crews, and truly maximizes productivity in your projects which results in increased profits.







The Leica GS18 I allows surveying professionals to measure previously inaccessible points quickly, easily and accurately. Now they can capture hundreds of points in minutes, safely and efficiently, and decide later which points shall be measured.
